the name, callosa, being preoccupied, would have to be 
changed). 
Vertigo decora (Gould, Pupa). Columbus, cited by Surface. 
The place seems to be outside of the range of its distri- 
bution, and probably pygm@a was mistaken for it, 
which I received, as “‘modesta,”’ fromthelate Hy. Moores. 
{Vertigo tridentata Wolf. 
Summit Co.! (Pettingell); Cincinnati! (Billups); Troy! 
(Shepherd); Tuscarawas Co., Columbus, Hamilton 
. (St.). Probably all over the state. 
{Vertigo parvula Sterki. 
Summit Co.! (Pettingell). 
Vertigo gouldii (Binney, Pupa). 
Summit Co.! (Pettingell); Portage and Tuscarawas Co.s 
(St.). Probably over the state. 
COCHLICOPID 
Cionella lubrica (Miller, Helix), Cochlicopa lubrica, Ferussacia 
subcylindrica auctt, not Linné. 
Over the state. 
SUCCINEID&. 
Succinea ovalis Say, obliqua Say. 
Cincinnati; Medina and Tuscarawas Counties. (rare, St.). 
Succinea retusa Lea, ovalis Gould. 
Over the state, common and variable. 
Succinea retusa higginsi-Bland. 
Sandusky; Put-in Bay; South Bass Id. (Walker). Seems to 
be a form of retusa. 
Succinea aurea Lea. : 
Cincinnati. The Cincinnati conchologists have regarded it 
as a distinct species; others regard it as a form, or 
variety of retusa. Not being familiar with it, I am 
unable to judge on its merits. 
Succinea avara Say. 
Over the state, common everywhere. 
Succinea avara vermeta Say. 
Tuscarawas Co. (St.). 
It seems that this form is not simply an incidental form of 
avara, being absent at many places where that sp. is 
common, but more or less prevalent, or common at 
some stations, and consequently a variety.
